ABSTRACT:
An estimated vehicle speed detection apparatus for motorcycles calculates an estimated vehicle speed based on a front wheel speed and a rear wheel speed and applies antilock brake control to each of front and rear wheels based on a calculated estimated vehicle speed. The apparatus includes a memory for storing the estimated vehicle speed at the time an application of antilock brake control to either the front or rear wheel is started, or an application of brakes to either the front or rear wheel starts. The apparatus further includes a calculation unit for comparing the front wheel speed and the rear wheel speed to calculate the estimated vehicle speed based on the higher of the front wheel speed or the rear wheel speed, while antilock brake control is applied to the front or rear wheel or either a front brake or a rear brake is applied. In this case, the rear wheel speed does not exceed the estimated vehicle speed previously stored in the memory.
